INSOIJE FOR SHOES.

Specification of Letters Patent.

Patented May 25, 1920.

Application filed May 3, 1915. Serial No. 25,470.

To all whom it may concern:

Be it known that I, ZAoI-i J. MONTGOMERY, a citizen of the United States, residing at Frankfort, in the county of Franklin, and State of Kentucky, have invented certain new and useful improvements in Insole for Shoes, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in welted boots and shoes and more particularly to the manner of attaching the upper and welt to the inner sole, and has for its object to product a boot or shoe of this character which shall combine maximum strength and flexibility and minimum weight resulting in reduced cost of manufacture.

Heretofore, it has been the common practice in the manufacture of boots and shoes to employ a relatively thick insole which is split or channeled around its edge to form the rib or lip to which the upper and welt are usually attached. This construction is open to the objection that the employment of a thick insole renders the finished shoe less flexible, than otherwise and also that the insole is weakened by channeling the same, such weakening resulting in the likelihood of the upper and welt breaking away from the insole. In order to overcome the above objections, it is proposed in the present invention to use an insole of relatively thin and any suitable material which necessarily will impart added flexibility to the shoe. Furthermore, in contradistinction to the common method of forming the rib, the present invention contemplates the use of a separate strip of canvas or other suitable material which is sewed or otherwise secured to the insole intermediate the longitudinal edges of said strip leaving said edges free to be turned up and secured together, preferably by cement, to form the rib to which secured the welt and upper of the shoe.

A further object of the invention is to facilitate the manufacture of the shoe by channeling or skiving the insole adjacent the rib and on the inner side thereof, so as to guide the inseamer in the inseaming operation, and at the same time, reinforce and strengthen the rib where the latter is joined to the insole.

The inventive idea involved in this in vention is capable of receiving a variety of mechanical expressions, one of which, for the purpose of illustrating the invention, is shown in the accompanying drawing; but it is to be expressly understood that said drawing and the particular, construction shown therein and described in the specification, are employed simply for the purpose facilitating the description of the invention as a whole and not for the purpose of defining the limits of the invention, reference being had to the claims for this purpose.

Referring to the drawing Figure l is a perspective View of the insole with the rib attached;

Fig. 2 is an enlarged transverse section of the insole as shown in Fig. 1; and

Fig. 3 is a view similar to Fig. 2 with the welt and upper attached.

In the drawing, 1 indicates the insole which is preferably made of a thin piece of leather of uniform thickness throughout, but which might be made of any other cheaper suitable material. This insole is not provided with the ordinary slits or channels which form the rib or flange to which the welt and upper are usually attached, and the edge portion of the insole is consequently of the same thickness as the body portion thereof, thus rendering it possible to employ an insole of considerably less thickness than is required for shoes constructed in the ordinary manner, and consequently, imparting a greater degree of flexibility to the shoe.

A strip of canvas or other suitable flexible material 2 is secured, intermediate its longitudinal edges, and perferably by a double row of stitching 3, to the insole 1 adjacent the edge thereof, as clearly illustrated in Fig. 2. After the strip has been thus secured to the insole, the free edges 4 of said strip are turned up and a suitable adhesive such as cement, is applied thereto in order to secure said edges together to form a rib or flange 6, to which the welt and upper are sewed.

The insole 1 is further provided with a cut or channel 7 which forms a lip 8 adjacent to the rib 6 and on the inner side thereof, constituting in efiect a facing for said rib. In manufacturing the shoe the edges of the upper, 9, are turned over the edge of the insole, and together with the welt 10, are sewed to the rib 6 by stitching through the lip 8, and the said rib, as clearly illustrated in Fig. 3. The operation of attaching the upper and welt is greatly facilitated by the employment of channel 7 as a guide for the,

whereby the liability of breaking is ob-.

viated. I

From the foregoing description, it will be apparent that insoles made in accordance with this invention not only reduce the cost of production of the finished shoes, but

greatly strengthen the same and render them more flexible than will the insole no commonly used. V

laying thus described the invention, what I claim and desire to secure by Letters Patent is 1. An insole for shoes comprising a body portion and an edge portion of uniform thickness, a rib consisting of a strip of flexible material secured intermediate its longitudinal edges to said body portion, and means associated with said rib and lying along and adjacent to the inner face thereof to form a guide for the inseamer.

2. An insole for shoes comprising a body portion. and an edge portion or uniform thickness, a rib consisting of a strip of flexible material secured to said body portion, and a facing for the rib constitutinga reinforcement therefor and at the same time providing a guide for the inseamer.

3. An insole for shoes comprising a body portion of uniform thickness, and a rib consisting of a strip of flexible material secured to the body portion, said body portion being channeled to provide a guide for the inseamer.

4. A shoe having an insole comprising body portion of uniform thickness, a rib consisting of a strip of flexible material secured intermediate its longitudinal edges to the body portion, the latter being channeled portion of uniform thickness, and a rib consisting of a strip of flexible material secured to the body portion, the said body'portion being channeled upon the inner side of said.

rib to form a lip adapted to reinforce said rib when the upper and welt are sewed. thereto.

7. vAn insole for shoes comprising a body portion of uniform thickness,and a rib consisting of a strip of flexible material secured intermediate. its longitudinal edges to the body portion, the free edges of saidstrip being cemented together, said body portion being channeled to form a lip adapted toreinforce said rib when the upper and welt are sewed thereto. i

8, An'insole for shoes comprising a body portion of uniform thickness, and a rib consisting of a strip of flexible material secured intermediate its longitudinal edges to the body portion, the free edgesof said strip being cemented together, said body portion being channeled to form a lip adapted to guide the inseamer when attaching the upper and welt to the insole, and also adapted to reinforce said rib when the upper and Welt are sewed thereto. 3

In testimony whereof I have afiixed my signature in presence of two witnesses.
